Golden Retrievers are one of the most popular dog breeds in America. A random sample of 20 Golden Retriever owners were asked about the weight of their dogs. The average weight was 70.1 pounds with a standard deviation of 5.4 pounds. According to breed recommendations for Golden Retrievers, the average weight of these dogs is 65 pounds. Test whether this sample provides evidence that the average weight of Golden Retrievers is greater than 65 pounds at the 5% level. (20 points) a. State whether the following variable is categorical or quantitative. Weight of Golden Retrievers (in pounds): b. State the null and alternative hypotheses.
